UWS budget dinner (early bird OK)
Ouest has a relatively cheap Prix Fixe before 630 I think. $33 for three courses. Not rushed when I've done it, and very good food.
Celeste and Gennaro's are both good italian, and won't be too busy earlier in the night. Cash only. At Celeste get the pizzas and cheese plates, and at Gennaro's the fresh pastas are really good.
La Rural up on 98th (?)and Amsterdam is also good for meet and Argentinian, cheap and have a great outside garden to eat in.
Greek, there's always Kefi on 72nd, good food, but gets crowded.
Chinese, not recommended on the UWS.
