If you are expecting small portion sizes like most French restaurants Mon Ami Gabi has excellent portion sizes. The service was above average for a Las Vegas strip property. The only downfall with this restaurant is that the seating is very over crowded. You are seated one on top of the other. We dined on a Saturday night and it was very busy, which is to be expected for a restaurant perched on Las Vegas boulevard. It seem as though the restaurant was focused on "turning and burning" tables. Average dinning time for other French bistros is a lot longer. We had a party of 4 and with appetizers and dinner we were out in less then an hour. Good if you want to get in a meal before a show.
The service was outstanding. Although the restaurant in my opinion was focussed on room turnover our waiter still took the time to help walk is through the menu. Overall good experience just really busy and very noisy.
