Having tried various Tex Mex places over here may I recommend Chi-Chi's in Piccadily Circus (opposite the Eros statue) [Leicester Square], in London - there Guacamole and salsa apperatifs are excelent ! Alternatively, if you just need a blow out- try theLone Star steakhouse, by Glocester Road tube station [London too]. There pepper sauces vary from the fruity to the wholeheareted 'Ring of Fire' specials. This place is relatively cheap for London, too. Andrew Healy
