Brunch (Pequeno-almoço reforçado ou pequeno almoço + almoço)

Na fim-de-semana passado (eu) fui para um "brunch" com as minhas amigas. Na cidades grandes, em particular, em Nova porque, os amigos conhecem reúnem-se / encontram-se para um brunch no sábado ou no domingo. Este é um tempo para comer entre café da manhã o pequeno-almoço e o almoço, geralmente entre as 1 PM 13h  (uma da tarde) and e as 3 PM 15h (três da tarde). (breakfast (pequeno-almoço)+ lunch (almoço)= *brunch). Os restaurantes desenvolveram um cardápio/ementa/menu especial só para o brunch, com alimentos do tipo: panquecas com frutas ou chocolate, pratos de ovos, e frango com waffles. Mas a primeira coisa que sempre pedir peço é uma mimosa! Alguns restaurantes estão são muito popular e (você/tu) poderia teria/terias de esperar 1 (uma) a 3 (três) horas para ser te/se sentado sentar/ sentares. A longa espera, no entanto, não impede ninguém, ele só confirma a quão bom é o restaurante. Se (você/tu) quer/queres visitar Nove lorque, (eu) definitivamente recomendado recomendo-lhe/recomendo-te a ter fazeres um brunch!

() = Option or information

This past weekend I went to brunch with my friends. In big cities, in particular, New York, friends meet for brunch on Saturday or Sunday. This is a time to eat between breakfast and lunch, generally between 1PM and 3PM. (breakfast + lunch = brunch) Restaurants have developed a special menu only for brunch with food like: pancakes with fruit or chocolate, egg dishes, and chicken and waffles. But the first thing you always order is a mimosa! Some restaurants are very popular and you can wait 1-3 hours to be seated. The long wait, however, does not stop anyone, it only confirms how good the restaurant it. If you want to visit New York, I definitely recommend to have brunch!

Brunch

OBS:

CORRECTION 

MISSTAKE

1 In Portuguese we dont say "Ter almoço"(Have lunch), we say "Comer almoço"(eat lunch) or "Almoçar"

2 I have no ideia what "mimosa" is

3 In English we say meet in two situations, "when you find someone in especific place like a meeting or when you start to know someone, in portuguese we have two verbs to do this:

"Conhecer" = Start to know a place or a person Ex: Prazer em te conhecer (Nice to meet you)

"Encontrar" = Go and Find some one Ex: Me encontre no meio do caminho (Meet me halfway)

4 "amigos se encontram no brunch no sábado ou domingo" it is correct, its a direct translation of that, but another way to say it is:

"amigos vão comer brunch no sábado ou domingo" (useing verb "ir"[GO]) Friends

5 Sorry for my english, i've studying it, however, it is not good enough yet.

Yellow, little mistakes.

Cyan, suggestions of words.

*Did you remember? This is not good to translate a sentence word by word. In this case, "I went to brunch" sounds better if you say "Past weekend I had a brunch...." because you have created a new noun (brunch) that probably does not exist a verb to this noun, yet. But if you want to create a verb in Portuguese to describe this noun, you can say: "eu fui brunchar com meus amigos" or "eu brunchei com meus amigos" but you will have a big headache to explain this verb.

friends "meet" for brunch: "to meet" in Portuguese also means "reunir", "encontrar". In this case, sounds better if you say "amigos encontram-se para o brunch"
