What a HUGE DISAPPOINTMENT!!!  I took my BF here for his birthday dinner.  We wanted a very formal dining experience, so we had made a reservation at RM Upstairs.  We arrived about 10 minutes early for our 8pm reservation and was seated immediately, and we were greeted timely by a waiter who took our drink orders.  After waiting a while for our drinks, we were ready to place our dinner order, which we did.\n\nWe wanted to start with the Seafood tower and the baby octopus.  We were asked if we would like to have these items together or separately, so we told them we would like them together....only to be told that they come from separate kitchens, so they may not arrive together....so what was the point of asking if we want them together?  \n\nWe ordered our entrees - I ordered the Scallops and he ordered the Arctic Char - he was really excited about ordering this dish.  He had scoped out the menu before we got to Vegas and he knew what he was ordering before we sat down for our dinner.\n\nOur Seafood Tower arrived and everything was fresh and delicious.  Then we sat and sat and sat and waited for our octopus dish to arrive.  Then we sat some more....when finally our tiny little octopus dish arrived.  We devoured the dish since it was so tiny, but i t was definitely tasty.\n\nThen we waited......and waited.....and waited.  We actually saw a guy sitting in a booth by himself having the 7 course pre-fix, and he was literally falling asleep and nodding off in between courses...I guess we weren't the only ones WAITING!!  We also totally felt ignored by this point and the place wasn't even busy!!\n\nAbout 2 hours after we were seated, the waiter brought us our entrees.  My scallops looked great, then I looked at my BF's dish.....salmon???  He told the waiter that he did not order salmon, and the waiter's response was....we don't have Arctic Char tonight and we're substituting it with salmon....WTF???  My BF was trying to keep his cool and told the waiter that he was not told of this substitution.  The waiter told him to please wait and he'll talk to the manager.  About 5 minutes later, he arrived and told my BF that he can choose something else from the menu and he'll have the chef prepare it right away.  In the meantime, I also returned my scallops because I was not going to eat them by myself.  I asked the waiter nicely to please serve our entrees together.\n\nAnother 15-20 minutes passed, and the waiter finally brought out our entrees.  By this time, with no apology from the manager or anything, we were fuming!  Our whole dining experience was ruined and we honestly didn't feel like eating anymore.  My scallops were not fresh anymore...I think they had it sitting under the heating lamp all this time while they worked on my BF's new dish, and just re-served it to me.  It was not hot and kinda gummy by the time I got it the second time around.\n\nWe told the waiter that we just want our check and leave.  Then the manager shows up and asks us what's the problem.  We told him the whole story of the long waiting, not getting our appetizers together, wrong entree (or not being informed of the change in the menu), slow service, etc. etc. etc.....and told him we were really disappointed in our meal and our special occasion was pretty much ruined, so we would like our check and leave.  Then he asked how can he make it up to us....don't you think that's a tad bit late for asking that?  He said he would take care of us and asked us to order dessert but we just simply refused.  It was almost 10:30pm and we wanted to get out of there.  Then he sends another waiter with some petit fours with \"happy birthday\" written in chocolate sauce and some tea service and that waiter told us there will not be a bill and just walked away.\n\nWe felt really uncomfortable and uneasy about not having to pay for at least the appetizers that we consumed, but once that last waiter walked away, no one came back to our table.  No waitstaff, including the manager even looked our way after that.  So we left what we would have originally left as a tip for our $200+ dinner on the table and left feeling very uncomfortable.  We just wanted a nice dinner out and we weren't trying to get over on anyone by not paying.....we go out to wonderful restaurants all the time for the food and experience, and this was the first time ever that we left what was supposed to be great restaurant by a fantastic chef feeling so very disappointed by the overall experience.  \n\nWe actually had another reservation at RM Seafood Downstairs for the following Sunday, but we called and cancelled our reservation.....there was no way we were going back there again.
