Paddys Market must be one of Glasgow's best kept secrets. Originally an Irish flea market for the poor, it is still a place to find unexpected things. Open every day.
Wondefrful old market open every day of the week except Sunday. Sells tons of different things including lots and lots of clothes. Everything cheap and according to urban myth, somethings "hot". Enjoy haggling and if you are looking something specific ask the dealers as they can get it for you in 24 hours probably
