Day or night, this place is awesome to check out. For weekends, this is my go-to brunch place. It's one of my favorites I've been to in the area. The food is great and they offer a Bloody Mary bar on Saturdays as well as "Mega Mimosas."
During the week, I'll normally be found here Wednesday nights when they offer $2 drinks from a wide list of specified options. Bring your friends and everyone can get a round for cheap. They've got other assorted deals depending on the weekday, so be sure to check them out to find out which day is best for you.
West End Tavern can get pretty crowded on weekend nights. That being said, you can expect to wait a while for a drink. I've typically seen 2 or 3 bartenders working and the bar area is not extensive. If people are hanging out at the bar, I've had times where it's taken about ten minutes to make your way to the front and wait to be served. The staff has always been nice throughout all of my visits and I'm sure the amount of people packing the place has got to be way more overwhelming for them than the wait is for me.
