24 hour shops/supermarkets?

Morning all, I've found myself working at all odd hours recently meaning I sometimes have to nip out to grab a couple bits between 1-6am. Does anyone know of any 24 hour supermarkets or corner shops? Anywhere in Leics is fine, I already know about One stop on Evington Rd and Asda at Fosse Park (Although the Asda isn't true 24/7 since they close at night on weekends and mondays)

Cheers in advance
