Stopped by early Tuesday evening. Restaurant not very busy. Chloe was our server, very friendly and bubbly. I like the variety on the menu. A good variety where most people can find something to eat. I ordered the briscuit sandwich. For $15 i expected a huge sandwich heaping with everything they described on the menu. What I received was a small bun with maybe 4 oz of meat and two little ramekins of toppings.
My wife ordered 2 tacos. The tacos tasted good but had very little filling in each one. Again at $5/taco with no sides these are pricey. We were both hungry after eating our food and ordered pecan pie. The pie was good whole pieces of pecans on top but no pecans in the filling.
A 1/2 hour later after I left I was still hungry. Not sure where the whiskey comes into play with the name. They had an extensive beer list but I didn't see a similar whiskey list.
Treehouse might work as a place to go to after work for a drink but as a dinner destination there are better alternatives.
