Honestly, I would just make the trek to Costa Mesa! Mitsuwa off of Bristol & 405 has a great food court in their grocery store. Especially if you want to buy a bunch of random other foods/drinks! And their bakery is yummy
How near is near? For example, is the South Coast Plaza area of Costa Mesa in your range? Because there's a couple of places you may want to check out:
• The food court in Mitsuwa off Bristol and Paulrino. If you like Japanese food in a super casual environment, it's great!
• Aloha Hawaiian BBQ…
“Costa” (Peruvian) on Anton near South Coast Plaza. Went there on a whim as it’s within walking distance from my place and it was amazing. You can pick anything and it will be good. Do suggest Loma Saltado. Best I’ve ever had.
