While in Vegas, my better half was looking for a Pho fix. SEA at Bally's was the closest and we were happy with the decision. Yes, it is extremely pricey for what it is, but that's Vegas...
Thai cuisine on one side of the menu and Viet on the other. BH had pho, which he said was good. I went with one of my Thai standbys, drunken noodles which was good and spicy, as requested. Dinner for two: drinks, appetizer and 2 entrees was $90 after tax and tip. Service was pleasant, no complaints there.
(TIP: ask for the sauce tray which includes siriracha and hoisin sauce)
