Is Lima within the best Food Cities in the world?
You should proof yourself.  Is not only that its top restaurant, Central, has been in the last 3 years within the World 50 Best Restaurants; this year, Maido, in the 8th; and Astrid & Gaston in the 33rd place… but you can also go to any recommended restaurant in Lima and you can still have a great experience in your lunch or dinner, or, even in your breakfast at your hotel.
How, in the last years (about 10?), we have grown so far? Our food was not discovered? It seemed to. Peruvians are happy to thank Mr. Gaston Acurio for this achievements, as he was the leader of this movements when he moved to Paris to have culinary studies at Le Cordon Bleu. Once back, he developed the Peruvian ingredients with all new tendencies and glamour to offer the Peruvian dishes at a higher level. More chefs of course learnt and were involved after that.
Another big social movement involved in this culinary and restaurant stuff was all the process in having our ingredients grown in remote areas to arrive in a restaurant in the capital of Peru, Lima.  Peru is a very diverse country with difficult geography making transportation and logistics a big issue. All the farmers and workers involved in this chain were now moved to the big scene, and not behind… That also made all the population to move eyes and see the whole activity, acknowledging that there are several personalities in the process.
If you do not get a table confirmed at Central Restaurant, do not be dissapointed!  Lima and in general all the cities and towns in Peru have plenty of top qualified restaurants that I am sure you will be more than satisfied.  We are the mentors not only in Lima, but in all Peru, as we have visited most of the restaurants and hidden places to suggest the best.  As we are pretty sure that Lima is one of the best Food Cities in the World, we offer the travelers experiences including visit of markets, visit of towns to taste local deserts and traditional recipes, encounters with chefs, and getting to know more why Peruvian food is every day more and more recognised. 
I live in Lima and cannot stop trying different restaurants and new options to always suggest my guests, this includes a good coffee shop (the best ones are those offering grains brought from the Central and Northern cloudforest of Peru, areas like Cajamarca and Amazonas), the best cevicherias (for sea food), the best sushi bars (Lima is known as the best city to have sushi in South America), the best place to have a traditional Peruvian restaurant (with fried sweet potatoe, tamales, deep fried pork, etc), and so, on, I will not stop..
If you don’t like museums, archaeological sites, historic sites, cultural exhibitions, historic heritage, ocean views, architecture… you can still visit Lima for several days to enjoy its food!
