We visited on a weekday evening, just after 6 PM, and the service was fast. The food quality was good—especially the takoyaki, salmon sashimi, rolls, and noodles. However, some of the allergen symbols seemed unreliable, and there weren’t many vegan options available. The sushi portions were also a bit smaller than usual.

A very good location for Trieste. Good food, friendly staff and the place looks very nice and bright. The only downside is the parking is a bit difficult to find. I will be back with pleasure!

Since the place is “all you can eat” and the media is the tablet you use to order is really you get what you pay for. More smiles would give it a 5 star in service. Food is really nice but not a “wow” quality.
