Thanks for stopping to read mmm-yoso!!! It's a food blog with three primary contributors: Kirk, Ed(from Yuma) and Cathy. The guys are otherwise engaged and Cathy is writing todays post.
I wrote about Kula before this Kaiten-zushi chain opened a storefront in San Diego, two years ago. Getting there at opening is the best way to find a free parking spot; there's a new parking structure around the corner which charges you for the privilege of parking.
There is a Kyobee tablet (like an iPad) out front where you sign in, leaving your mobile number, which will notify you of how much longer your wait will be (and eventually tell you to 'Get back to the entrance!!!') . Again, get there at the 11 a.m. opening and viola! no wait. 
There are booths as well as bar seats for those wishing to eat alone (or not wait for a booth). The conveyor passes all of the seating areas. 
The first plate 'announces' what the following three plates contain and you can choose one by grabbing the edge of the covered plate and the protective covering lifts up. All of the choices from the conveyor are $2.25 each. 
Scallops, seared yellowtail, two pieces on each plate were a good portion.
The large pieces of tuna were very fresh. 
This was the 'spicy popcorn shrimp roll'- two pieces of fried shrimp with a spicy sauce and masago on top served on top of two slices of crab roll. 
By far, the cucumber salad was my favorite this warm day; a fancy version, it comes with tamago, cuts of fish, octopus (or squid), and seaweed. Topped with some crunchy sesame seeds, it's a light meal in itself. The vinegar based dressing is refreshing.
At each seating area is a tablet with an order panel for additional items. There is a 'countdown clock' so you can expect the arrival (and know it is being prepared fresh). The item shows up right at your table, on a second belt. We ordered a few things.
The tempura vegetables with shrimp on rice ($5.80) was quite perfect in its fry technique. The rice was good to have with the rest of our meal. this came with a bowl of miso, making it a complete meal. 
The soft shell crab ($4.20) was another good choice. Again, perfectly fried 
We also ordered 'crispy squid' ($3.20), which was plentiful and fried just right.
When you are finished, you slide your green (from the conveyor) plates in that slot so they are counted. There are small 'prizes' that are discharged from a machine above the top belt, but you have to have inserted 15 plates to get that trinket.
All in all, a fun experience.
