I was introduced to Mexican Food by my girlfriend, and was quite disappointed to fine that London lacks a wide variety of Mexican restaurants. Of the few that are on offer I would say that La Perla is by far the best, and I would say that it is up there with some of the traditional Mexican restaurants I have eaten at while in America.
They offer a full Mexican menu, from starters to dessert, and I would personally recommend the nachos for starters and the vegetarian Burrito for main, which is huge. For this meal you are looking at paying around £11, which considering the location and the quality and quantity of the food, is excellent value.
Along with a good food menu, there is also a good selection of drinks, cocktails and of course tequila, and if you have a little spare cash then you could try one of their 99 Pounds a shot tequila. It has to be high quality liquor at that price!
Opening hours are as follows:
Mon-Sat 12.00-23.00
Sun 16.00-22.30
Although I have never had any need to reserve seating here, with a capacity of only 40 people it may be wise to do so if it is an important occasion.
Another good point about dining at La Perla, is the location. Almost directly over the road is my favourite bar in London, The Porterhouse, which has over 300 different beers on offer, as well as numerous clubs and other bars in Covent Garden.
The nearest tube stations are Goodge Street and Covent Garden, both of which are no more than 5 minutes walk away.
