It takes only a meagre command of Spanish to translate the first two words of the name, which derives from the two friends, Robert Aylwin and Aaron Calman, who established it almost two years ago (although they have not since updated the website, where the winter of 2010 is still in the future). Those more familiar with Spanish vocabulary will know that a cantina is the name applied, on both sides of the Mexican-United States border, to a place whose customers' primary purpose is drinking.
I make the point because diners who head to Dos Amigos expecting a Mexican restaurant may be disappointed. Of course it serves food - more of this below - but the atmosphere, even in the dining area, was closer to a rowdy bar the night we visited.
This effect was perhaps heightened by the presence of a boisterous octet of males preening their chest feathers as they did tequila slammers at the corner table, but Dos Amigos tends to encourage the approach: there's a hefty discount if you buy your beer by the bucket (an ice-bucket, you understand; the beer is in bottles) and tequila gets a page to itself in the menu.
So do margaritas, although they may not all be entitled to that name. Our basic model was more like a lemon drink with a whiff of alcohol - suitable for beachside thirst-quenching perhaps, but not what you would call a heart-starter.
Dos Amigos has a nicely raffish feel to it: the walls are lined with rough demolition timber and corrugated iron, and the tables are snugly, even tightly, packed. The service is a little vague and the wait must be hideous when it is packed, if our experience on a quarter-full evening is any guide, although they make the point on the menu that they don't make fast food. What they do make is perfectly palatable but it would be a stretch to call it remarkable. The Mexican food in Auckland is generally shocking - with the honourable exceptions of El Camino in Kingsland and the resolutely unusual Mexican Specialties in Ellerslie - that it doesn't take much to stand out from the crowd and Dos Amigos' food is at least freshly made, as opposed to some of the bain-marie blah that gets packed into taco shells around town.
Quite what buffalo wings are doing in a Mexican restaurant is anyone's guess and the absence of ceviche from the menu of a harbourside place is very puzzling. But the fajitas, which arrive on a dramatically sizzling platter to be assembled by the diner, are made with excellent beef. By contrast, the burritos were rather meanly overstuffed with rice and are more filling than fabulous.
The major gripe is that the food lacked any real zing: the chicken mole (a chocolate-sauce classic) was positively bland in look and taste. Some dishes are indicated as being "picante" but a bowl of salsa on the table and a slightly more adventurous approach by the chef is needed to elevate this place from the ordinary to the special.
