People that know Mexican food- Whats the verdict on those big department store Mexican restaurants?

I think theyre so scammy! I’m talking about those big ones in the department stores with the cool atmosphere and lighting. Every time I go to one of them I feel so cheated and unsatisfied. This time we thought the 3 bowl guac looked good. It’s like 1mm deep. The beef fajitas was like chewy rubber and the drinks were 90% ice. But everyone in here is vibing like it’s the best spot ever. I’m not asking for the ost authentic experience, I know where I am. But cant we at least get some quality meat? It’s crazy how packed these places always are .
