"Coming in on a chilly weekend, we stumbled on this ramen restaurant near the hotel with low expectations. I tried the Oisa Tonkotsu and the vegetarian ramen with shiitake. Both I had asked for the noodles to be slightly underdone as preference Moe, the chef and owner, was quick to explain that the noodles in the vegetarian ramen were cooked to a specific temperature otherwise can become quickly overcooked. It was doable, but not recommended. I went with her suggestion and wasn't disappointed. I also learnt that the noodles are made with tomatoes, which would explain this familiar taste that wasn't quite just shiitake I tasted throughout the broth. The Oisa Tonkotsu was my favourite however comparatively. Served hot, the broth was flavourful throughout without being too rich, the noodles springy and I loved the tang of the pickled vegetables and ginger. The meat was sliced thin, which I would've preferred more of but the extra soup and noodles I added made up for it. For those with bigger appetites, go this route. Service is quick and efficient, but don't come here if you're in a hurry; the place fills up fast and there's usually a small line. Solid bowl of ramen wrapped in a friendly and cozy atmosphere. I recommend sitting at the bar and chatting with Moe, an absolute joy to chat with. You can tell she is very passionate about the food. I'm coming back the next time I'm in Boston!"
