Ah, Bucket's.
This place has been in Union City for a long time now. I think I've had almost everything on the menu (although I noticed during my last visit that the menu has changed, so I guess I should say that I've had almost everything on the old menu). It is not the best food in the world; I mean, it IS standard pub food. What they do, though, they do pretty well pretty consistently. This is not an easy feat in Union City. A lot of places are good in the beginning and then end up sucking after about a year.
My recommendations?
Go with some friends. Sit on the bar side if you can. Make friends with the bartender (until recently, I knew all of the bartenders because I had gone to school with them, but I didn't know the guy that was working when we went). Order a drink; they're cheap and they're good. Try the Firehouse burger, any of the baked subs, the Baked Chicken Carbonara, or a pizza. I am 99.89% positive you will have a good time.
Besides, there's really not that much else to do in Union City.
