Oscar's Greenhouse

Oscar's Greenhouse Oscar's is "growing" this summer. We're taking over the rooftop on 3rd St. on the weekends from June through September (weather permitting).

We’re a fun, causal, summer destination serving cocktaiks, mocktails, beer, etc. Enter through The Firepit.

So we gave away our free martinis, for the weekend, in 2 hours! We SOLD OUT! It was insane! You guys really like free drinks.😂 So the “while supplies last” really didn’t last very long. AND we had someone step through a warped part of the landing. So with that, the Greenhouse is going to be closed tomorrow so we can make sure the floor is safe to walk on. We’re going to have crazy specials for next weekend because it’s likely going to be the last weekend we’re open. $2 and $3 beers, $4 and $5 cocktails! Watch for details, it’s gonna be crazy!

It’s actually a beautiful night to grab a drink on the rooftop! You don’t want to miss our frozen Pornstar Martini or NITRO Espresso Martini. We’ll be closing sooner than you think. Nights are getting colder and days are getting shorter. So stop up and try us before we close for the season! You can order our sandwiches from downstairs and enjoy them upstairs as well. $2 off our sandwiches tonight. Open until 11!
