If you're looking for solid ramen in the Peninsula without an insane wait, Ramen Seas is your place. It's located right in Downtown Sunnyvale. Great selection of ramen with plenty of add-in options.
Tonkotsu ramen is fantastic!! Small is the perfect size, regular is a bigger bowl of it if you're super hungry, and large has double noodles (of reg) if you're starving your face off.
The miso ramen is outstanding -- a really intense broth, with just the right amount of heat. The chashupork that came with it was also really tasty. The simmered gyoza were rather bland.
The miso ramen is great: wonderfully, sweet broth and noodles that are just the right amount of chewy. Who cares about the egg being slightly overcooked!
Still fairly new location-- the waitress offered to replace my meal if its not to my liking when I debated on trying the ramen seas special. (It was delicious BTW)
Kakuni tonkatsu ramen has smooth and rich broth. However, miso clam ramen with habaneros (spicy level 6/10) is too spicy that you can't even taste the broth :(
