The worst restaurant

Last night I was in a restaurant [this would be 'correct', but it might be more natural to say 'Last night I went to a restaurant' or 'Last night I ate at a restaurant']. I thought that it would be nice but it wasn't. Starting with the food: it was too cold and drinks weren't cold enough. The food was unsavory and there wasn't information about allergens on the menu. It was the worst food I have ever eaten [some native speakers would naturally double-up "ever" and "before" here, but it is not strictly 'correct'].
The waiters were so unfriendly and weren't fast enough. They got all the dishes wrong. They were unfriendly and never smiled at us.
The cost of the meal was so expensive considering the low quality of the food and the slow service. We felt horrible because of the bad service and food. We won't recommend it and we won't go back again [or, instead of "go back", you could use "be back", but this would be more informal].

My perfect restaurant would be nice and charming. The food would be healthy and tasty. The service would be fast and the waiters would be located close to my house [this is grammatically correct, but odd - why would the *waiters* be close to your house???]. The quality-to-price would be reasonable and I would feel great being there.
