As the sign says (charcutería, pizzería, panadería, pastelería) you can by a lot of different things at Roma. Roma is situated conveniently next to Posada Guamanchi where I stayed. It is also on the way to the Teleférico for many people. Early in the morning you can see the workers from the Teleférico stopping here to buy something and a little later people on their way to the Teleférico will stop here.
When I stayed in Merída I usually came here to buy breakfast, bread, yoghurt and coffee to take away and to eat on the balcony outside my room. Other things I bought here was chocolate, sweets, biscuits, juice and water. You can also buy things like pizza slices, empanadas, cheese and ham.
There are a few tables where you can sit down to eat.
This is the one stop shop for all your gift needs. The mercado has 3 large floors of everything you could want to buy from merida. The first floor has many stalls selling food, drinks, and Andian sweats. Look around for the deals as many often give 2 for the price of 3 etc. Merida is well known for many differnet sweats (candies) and cakes so you can really stock up on some great treats here. Merida is also known for many different flavors of liquor - some that just make you plain drunk and others that are supposed to have magical healing qualities. All are available here.
The second floor has a lot of handicrafts and T-shirt vendors so you can buy many gifts to take home as memories of your trip. You can buy everything here for yourself, friends and family - carved statues of Bolivar or Chavez, Amazon artwork, ceramic goods, keyrings, etc.
The last floor has a number of more expensive art boutiques with one of a kind sculptures and paintings as that extra special memoir, intertwined with vendors of odds and ends selling caps, cards, and some real tack.
You could easily spend a couple of hours here. There are ATM machines within the market if you run out of money as well as places to eat and drink coffee to keep your energy levels high.
Most of the prices here beat the prices in other parts of the city.
What to buy: Candies/Sweats typical to the region.
What to pay: huge range of prices here as there are so many different goods. Everything from very cheap tourist momentos to expensive sculptures
