Marios is always a fun time to hang out and grab a drink. Especially in the warm weather when the upstairs windows are open. Last night I went with a group that had the top floor reserved for us along with free drinks and apps. The service was good, sports games were in in the back and everyone had fun. As the night went on it started to get crowded, but never to the point where I felt claustrophobic.
This is a good Shadyside bar and usually attracts a lot of young professionals. There's also darts downstairs to play along with shuffle board. The bathrooms sometimes can get crowded. Otherwise it's a fun place to hang with good music and dim lighting.
