Yoshi is the best sushi place in Corpus. Their menu is very extensive and their chefs are very good. The fish quality is the best I've seen in Corpus, especially as someone who grew up eating Austin sushi.
They also have a large non-sushi menu. I've only ordered from it a few times and everything was delicious.
The staff is always friendly and usually very knowledgeable about the menu. The owners, Judy and Brian are always hands-on. They really care about this place and it shows in everything from the menu to the decorations.
