My trip to KGB is a little . . . fuzzy, but I was still full in the morning so I know the portions were copious.
I have noted multiple service complaints in the prior reviews. As far as I know, I (we) traipsed in there (not elegantly) at around 3 a.m. after being frequently offered beer during a few hours of play at Casino Royale and had no issues, were sat immediately upon requesting a table.
I was feeling saucy and so ordered a double cheeseburger of some kind with jalapenos and fries. Suz added an order of buffalo wings. The wings were wee little guys, but had a pleasing crispness; the sauce was pedestrian but I liked the tanginess of it.
The burger was gargantuan. Well, it seemed so anyway because I did not finish it, but the fact I'd earlier eaten a bone-in ribeye at Mastro's may have had something to do with that.
The cheese was melty and good; I vaguely recall the beef having good flavor and while it was a bit sloppy, it held together pretty well considering it's girth and height.
For a person in my state at a time like that, this was a very good experience. The food was hot and fresh.
I don't remember a whole lot about anything else in the restaurant, aside from the obvious Soviet theme.
