I have been to Tremont Tap House twice for brunch (I love brunch!). It has a great energy. Loud and active but I can still hear my friends talk. Parking is pretty easy. When making brunch plans, I usually mention Tap House. Definitely recommend.
Both times I sat at the bar and ordered the eggs benedict without the ham. (complaining - the hollandaise sauce is a little on the sweet side, but its probably because the salty ham isn't there to offset it). The waitstaff is nice enough. My refills on coffee and water have usually a little later than sooner.
