The Spanish Omelette is one of the best, a fact confirmed in the 5th National Spanish Omelette Contest. It’s golden on the outside but gloriously gooey on the inside.
It’s best to get there early, no later than 1 or 1:30pm and, if possible, during the week. There are less people and you’re guaranteed to get a pincho (they make a limited number of these generous portions and they go quickly).
I recommend you complement your omelette with an expertly poured caña of beer from the oldest Guinness tap in Madrid.
A pincho (1/5 of a Spanish omelette) + 1 large caña comes to 6.14 euros.
