I have had Ramen Isshin's main restaurant bookmarked for the longest time, and now that they've opened up right next to my workplace there's really zero excuse to not try them out anymore. The ramen is absolutely as heavenly as everyone else says (see other reviews on the other location for much better descriptions of the taste)! The broth is rich and smooth, the noodles just the right amount of chewiness and texture, the soft boiled egg to die for, and the flavour is exquisitely delicious.
Appetizers were average, but then that's really not the main point...service was very nice and friendly, given that this is a food hall downtown we're talking about.
Portions are definitely reasonable, although certainly not cheap. Urgh. Time to rethink my budget to account for weekly ramen splurges.
