Walked in GIADA w/o reservation for lunch on Monday.  we can ONLY use bar area even there are vacant table due to not enough server.\nwe ordered three items on the menu. both the Mushroom pizza and Tuna sandwich are on the salty side.\nthe WORST part was the response from the staff when we inform him there is PRICE DIFFERENCE on our bill.  He just simply said that he would need to look for a manager to take a dollar off the bill. W/O apologetic. NO interest to know what the misstate is.  FUNNY in this kind \"LUXURY\" restaurant.\nPLEASE spend some time to check the price in the system to make sure you bill the correct price accordingly!!!
