Two very different experiences in the same weekend.
Me and my husBAND ventured in for lunch on Saturday looking for a cool (physically cool) spot to regroup in. We were the only ones sitting inside, but were treated to friendly and efficient service none the less. The food was just very average and they didn't have a giant range of liquors to choose from. We had our 1 drink and our lunch and then moved on. Probably would have given them 3 stars based on that experience.
We returned as a large group on Sunday night late night (about midnight) after a nearby wedding. No one else on that strip of King Street was open so, by default, we all ended up here. We were treated to the absolute unfriendliest service that we experienced in all of Toronto (including the nasty cab driver that apparently hates King Street). None of the wait staff smiled nor did they act like they wanted us there. A couple of people were so turned off that they left before ordering their first drink. Some others ordered 1 and then left soon after. The vast majority of the group stayed and were treated with this attitude until they closed. I mean, I get 1 server in a restaurant possibly having an attitude, but the entire wait staff? COME ON!!!
We were talking to the bartender at our hotel about this experience the next day and she was shocked at this. She explained that Gabby's gets all of the late night crowd typically as the other bars close earlier. So, they are used to the random late overflows.
So, in summary, an OK spot to pop in for lunch for a quick bite, but definitely do not suggest hitting this place up late night. Unless you like being made feel like a hindrance.
