I've been here a few times over the years and it is always my go-to ramen spot. Returning earlier today, it has clearly gotten more popular over time as there was quite a wait at 3 PM. No matter. We had a beer at Sneaky Dee's and returned in time to be seated at the long bar against the back wall.
What impresses me most about Ramen Isshin compared to other places in the city is the variety of ramen on offer, all of high quality. There are several styles and flavourings and their vegetarian ramens are not merely an afterthought. The egg addition is a necessity and I usually request a second bowl of noodles mid-way through my meal as the broth is just too delicious to let go to waste.
