I wouldn't call it a Tavern... I'd put it more in the upscale gastropub category. Tavern implies dark, cozy, slightly antiqued. Big Grove is open, airy and modern.
The food was good but not phenomenal, but the drinks were great -- and thoughtfully recommended by our waitress, who was nothing short of fantastic. Seriously. I so often wish I'd kept track of servers' names, but this one I seriously regret because she deserves a wonderful review directly to her manager.
I'm sure I'll be back next time I'm in town.
