Mitasie Vegan Cafe in Lake Forest. They only have this location and their original location in HB (their HB location is a full service sit down restaurant unlike their LF location).
I also liked Huntington Ramen in Fullerton and Tama Sushi in HB, but I haven't been to them in a while.
I love all three of these places! I also commented tama sushi as well. I forgot about Huntington ramen! I used to frequent their HB location when I lived in HB. Same with mitasie. Now I live in RSM and I’ve done delivery of mitasie and was sad they didn’t have the hot and sour soup at the LF location.
