I have tried taiyaki at several places. Kevin's Taiyaki is by far THE BEST. They have custard, red bean, and black bean. They take the time to make them not only taste great look pretty as they trim the remnants of crispy bits off the fish before they sell them.
I was always a red or black bean fan but tried the custard and that is equally tasty. Always drop by if you/re in the hood. Buy some groceries from PAT and get your taiyaki treat on the way in or out!
