Germany is one of the most beautiful European countries and I was lucky enough to visit most of its big cities. And although I've spent only a few hours in some of them, I had a really nice and positive experience. Frankfurt was on my list for quite a long time, so when I had a day-off I knew where to go.
How to get to Frankfurt?
If you're not too far away from Frankfurt, I suggest traveling by bus. Flixbus is the most popular company in Europe and you can get anywhere for quite a low price(usually around 5-30€ around Germany). Another way to travel around Germany is by train (DeutscheBahn). It's slightly pricier, but you can get from one end of Germany to the opposite in just 2-3 hours. Both Flixbus and DeutscheBahn have apps that are super easy to use. You can also rent a car, but keep in mind that there's no free parking. Of course, plane is the best for those who travel from far away, although in this case you'll have to spend some extra time and money on taxi or public transportation to the city center. 
The main entrance to the Hauptbahnhof faces Kaiserstraße. The street is a bit dirty near the railway station, but it eventually leads you to the famous skyskrapers and the old town. When you reach Neue Mainzer Str. the city starts looking a lot prettier(at least it was like that for me).Follow Kaiserstraße deeper into the city and after Roßmarkt you will find yourself at the Hauptwache. On your right you will eventually see the the first parts of the old town appearing. This is where St.Katharinenkirche and most of the shops are located. You need to turn right to the Liebfrauenstraße and than follow the lovely Neue Kräme street into the heart of the old town. 
If you're looking for the best view on the city - go to the top of the cathedral called Frankfurter Dom. It's located in the old town and you can get there from Römerberg square. The etrance ticket to the Dom Turm costs 3€ and there's no elevator, so be prepared to climb a lot of staircases to the top. You can also go inside the cathedral for free.
The other way from Römerberg square takes you to Main and to the beautiful Eiserner Steg - the bridge to the other side of the river. I didn't spend much time on the opposite side, just took a few pictures and went back to the old town.
Where to eat?
There are plenty of restaurants and cafes for everyone in Frankfurt. Here are some amazing options in the city center:
Cafe Sugar Mama
A combination of amazing food, atmosphere and modern design. Located just near Alte Brücke and perfect for brunch. Plus, the desserts here are extra tasty.
📍 Kurt-Schumacher-Straße 2
Fame - The Sandwich Shop
Must be the best place with sandwiches in town. The restaurant is located on the other side of Main, in the area called Brückenviertel. The menu isn't limited with only sandwiches, so there is something for everyone to eat here.
📍 Wallstraße 10
Haus Wertheym
This one is located not far from Eiserner Steg and if you want to taste German cuisine - it's perfect for you. Not too fancy and quite traditional, but very delicious.
📍 Fahrtor 1
Fisch Franke
This seafood restaurant was first opened in 1920 and is kind of legendary in Frankfurt, that's why you may want to book a table in advance. I didn't have a chance to visit it, but the reviews are very good and if you have some extra time - go for it!
📍 Domstraße 9-11
Vevay
The name Vevay stands for Vegetarian Vegan Yummy and that's exactly what it is: fresh, healthy and meat-free. All the products come local farmers and suppliers and the reastaurant is located in the city center.
📍 Neue Mainzer Str. 20
