Tapas bar Estragon and Spanish grocery and sandwich shop Las Ventas sit side by side in the South End. Perhaps its this proximity that inspired Las Ventas bocadillo, which puts a tapas bar classic between bread. Tortilla espanola, that lovely omelet of egg, potato, and onion, goes into a good, crusty loaf with caramelized peppers and aioli. Its like an entire breakfast in one sandwich. D.F.
