I've been there maybe five or six times, but not very recently. I used to tell people that it's overpriced and some of the stuff on the menu might gross you out, but it's the most fun you'll ever have at a restaurant.
From my limited experiences, it's more fun to go for the later seating. The earlier crowd tends to be a bit more subdude.
When Sammy's is really rocking, it's like you've stepped into a low-cost 1950s bar mitz-vah. There is a guy singing and playing songs on a keyboard in the corner. The tables are very close to each other and the walls are completely covered with photos and articles. There are spontaneous line dances with people you don't know. There are make-your-own egg creams with dessert and seltzer in spray bottles on every table, as well as the previously mentioned schmaltz, which is in the sort of pancake syrup containers you see in some pancake houses and which is poured onto chopped liver, mashed potatoes, etc. It's actually the only place where I'll eat chopped liver.
And from my experience, even a small Roumanian tenderloin steak is enough for at least two, and maybe three people with all of the other stuff that you eat.
We always had a plate of very good ruggelah for dessert, along with the egg creams.
