I have eaten here before and the food is very good albeit at a price. Service last time was arrogant though and I see now where this comes from.
We tried to eat during the recent cold spell and it was a joke.
Freezing inside temperatures because the management is too mean to seal up the open doors or buy some temporary heaters meant we could not even sit down as eating in overcoats has never been our thing.
To make matters worse, when questioned politely why it was so cold inside the belligerent reply was "well, it is cold outside"... You don't say, Sherlock!
Sadly, this is only too typical of Mexican service where staff simply never get trained to understand customers want to be looked after and not argued with.
Spend your money here by all means but know they don't care at all. There are (a few) better places in Guadalajara - but not many as a Guadalajara generally does awful restaurants in my opinion.
