I visited here with various family members before. The food is fairly good value at £6-7.95 for all you can eat. The food is always good quality, tastes good and seems to be replaced nice and regularly.
The tables are cleared quite well although sometimes you end up with a stack of old plates it being all you can eat and several people at the table going back once or twice. The man you I think owns the restaurant (he's not in uniform the same as everyone else) works very hard cleaning tables and taking payments. It sometimes gets a bit too hot (not sure if there's no air conditioning or if it's just not on) and busy in the summer.
The girl at the bar isn't very friendly didn't smile once when serving us, said we had to pay for food at the till although it says at on the wall pay at the bar!, she doesn't seem to want to be there...
For a treat when visiting Cleethorpes I think it's a good place to go for dinner.
