Here's the deal with MIss Saigon 88...it's like every type of asian food, not just vietnamese. Everything is decent, but not like the best pho/sushi/korean/vietnamese/chinese food ever. If you have a craving, this place will do the trick.
The portions are pretty big and I would definitely recommend going when everything is half-price. I believe most nights after 8pm.
Since we were with a group, we got to try pretty much a little bit of everything.
Sushi - decent, I got the Tuna Lover Roll...as advertised, it had a lot of tuna.
Pad Thai - not really pad thai and more like pad see ewe or beef flat noodles. Tastes good, but not like pad thai.
Curries - really large and good flavors
Hibachi Plates - very large and decent
Fried tofu - fried well and nice and crispy. make sure to ask for the sauce on the side or ask them to go light on the sauce.
Rice plates - just ok, I probably wouldn't order it again. Nothing horrible, but it wasn't quite as good as most of the vietnamese rice plates I've gotten.
