After theatre drinks/lightfare
If you like wine here are a couple suggestions of places not far from the Goodman. Even if you dont like wine, either of these would still be a nice place to stop after the theater.
Just across the bridge from the Goodman is Bin 36, a place Ive mentioned several times. The lounge area has a mix of tables, booths, and sofas and would probably work well for a group of 8. Its sort of elegant/industrial décor and is usually fairly lively but not overly loud or smoky. They have a well-chosen list of 50 wines by the glass that top out around $12, the standard cocktails, and a limited draft beer selection. Theres a pretty good selection of snacks like interesting cheeses, house-made pates, and small pizzas. They also serve some more substantial dishes and desserts which I havent tried.
Another good place thats vaguely similar is Randolph Wine Cellars, right across the street from one sixtyblue (this would be a short cab ride from the Goodman). Like Bin 36, wine is the big reason to come but theres plenty of other good stuff. Its a little darker and quieter than Bin 36 and the upstairs room would be good for a group. This room is very nice, with big windows facing the skyline. It used to be much more open but now they have filled it with all kinds of sofas and chairs (looks like a furniture showroom, said a friend). A great selection of 50 wines by the glass, topping out at about $25 (a fair choice in the $5 range too). The thing to remember is on Monday all by-the-glass wines are half price. Food is limited to cheese, pates, and desserts. I havent eaten anything here but I bet its good.
