Conveyor belt sushi restaurant revisited

As last week went to an inexpensive conveyor belt sushi restaurant for lunch with 20 people, went another conveyor belt sushi restaurant with reasonable price for lunch again.
The sushi restaurant this time has no colored distinguish for ordered dishes, which causes a mistake to take others' dishes frequently. The taste at the restaurant lase week was better than one this time but the restaurant was sooooo crowded with lots of families. All the seats (tables with 6 people in maximum) were full for a long time.
"Rotating sushi" seems Japanese English and have no idea to translate simple kinds of fishes such as tuna, salmon, octopus and squid. Shells were just "shell" for me...
It was worth to spend and a nice time on holiday's morning.
