The food alley is the busiest street in Salzburg's old city. This is also a small street that best reflects the European style of the Middle Ages. The facade of each building clearly shows the age of construction. The most striking thing is that every business has its own signboard. The signboard is made of metal and retains the style of the 16th century, which adds a lot of elegance to the food alley. The houses preserved in the Middle Ages are now renovated, and the quiet, tree-shaded houses contrast sharply with the crowded scenes outside the courtyard. The shops on this shopping street are very distinctive, with famous brand shoes and hats, home clothes, gold and silver jewelry, and tourist souvenirs. The No. 9 Food Hutong is Mozart's former residence. It's very busy here. There are plenty of places to eat in the food alley. There is a YUAN cafeteria opened by Hong Kong people beside the 20 Getreidegasse, one person in 10.9 Euros. Food Hutong is also a famous seafood restaurant gathering place, where crowds are gathering, and the food tastes and prices are good. The famous local fast food Nordsee, fried fish and prawns are fresh. The most authentic Mozart chocolate shop is on this street. The blue and red packaging is very beautiful, but the price is not low, about 1 Euro a piece. Nearby Billa Supermarket is cheap "Mozart Ball" (a kind of chocolate), 2 Euros more than a bag of nearly 20. It's 20 minutes'walk from the railway station. With regard to tax rebates, non-EU tourists can apply for tax rebates if they buy more than 75 euros in duty-free shops. When shopping, you must ask the salesman for the tax refund form and fill it out by the salesman. When leaving customs, the goods purchased are submitted to the Customs for inspection. After stamping the tax refund form, the customs can collect tax at the airport or at the border.
