Well, you can't wish to have a 5 star treatment in such kind of restaurants.
I can assure, the food is not bad, in fact good. Quantity is a plus point over here. Order 1 rice/noodles & that should be enough for 2. Starters/soups are good. Go to this place when you don't want to cook on weekends. Don't go in a large group. You’ll have to wait a lot and large group seating is not that comfortable (chairs are really bad, feels like seating on railway platform).
+ve s:
Good food, quantity, price, location
-ve s:
Unhygienic, A/C doesn't always work, ambience, waiters..
