For me, Greg's has always been a staple of icecream in the city. They have a diverse selection of flavours everyday, and my go-to scoop had always been the roasted marshmellow. I tried one with lime (forgot the name!), and I highly recommend it as well. While this is a lovely little place to visit after a meal, there aren't many seats in the store; be prepared to stand or walk. If you want to try different flavours (especially after a meal), I recommend the half scoops because their portions are quite large. The staff are nice and really help you out with choosing your flavours. The downside to Greg's would be their lack of waffle cones. That would've been a nice cherry on top :)
